1.2 Does BRB-ArrayTools work on a Mac machine?

3.2 I have a custom array –how can I import my annotations?If you have a custom array, as part of the importing step, you can specify that you haveyour own gene identifier file and would like to use this file to annotate the data. Thesoftware will read in this file to create the gene identifier and the corresponding geneannotation <strong>work</strong>sheets in the project <strong>work</strong>book.3.3 I get an “Istatconnector error” during data import step. What do Ineed to do?The reason for this could be because the file path contains some non-English charactersor that the file/folder name is too long. Please, ensure that you use only “English”language names for your raw data folder and files.Also, that these names do not includeany special characters.3.4 I got a Run time error 75 when importing the data. Please, help.This sometimes happens to VISTA/Windows 7 users. If you have not modified thepermissions to the “<strong>ArrayTools</strong>” installation folder, you could see this error. To viewinstructions on how to change the permissions to this folder please, review thepresentation available onhttp://linus.nci.nih.gov/~brb/download_individual_new_v4_1_0.html4: Analysis4.1 How can I learn some of the features in the new scatterplot tool?Please view the video available onhttp://linus.nci.nih.gov/PowerPointSlides/Scatterplot.wmv4.2 How do I exclude arrays from an analysis?Suppose, for example, that you want to find genes differentially expressed between celllines of lung cancer and cell lines of breast cancer. Set up a column in your experimentdescriptor <strong>work</strong>sheet that has a code (e.g. LC) for the lung cancer cell lines, a differentcode (e.g. BC) for the breast cancer cell lines, and is blank in the rows for the arrayscorresponding to other types of cell lines. The arrays with the blanks in that column willbe omitted from the analysis. You will find that you create many new columns of yourexperiment descriptor <strong>work</strong>sheet as you proceed with your analysis as you think of newcomparisons you’d like to do. You can easily add columns interactively within <strong>BRB</strong>-<strong>ArrayTools</strong>. When you re-save your project, the changes are saved.
